NAME
       polyhedra - draws the 80	uniform	polyhedra and their duals

SYNOPSIS
SYNOPSIS
       polyhedra  [--display host:display.screen] [--visual visual] [--window]
       [--root]	[--window-id number] [--delay number] [--speed float] [--dura-
       tion seconds] [--no-wander] [--spin  XYZ]  [--wireframe]	 [--no-titles]
       [--which	name] [--wireframe] [--fps]

DESCRIPTION
       This  program renders 160 different 3D solids, and displays some	infor-
       mation about each.  A new solid is chosen every few seconds.

       There are 75 uniform polyhedra, plus an inifinite number	of prisms  and
       antiprisms:

	 * Convex Uniform Polyhedra:
	   * Platonic solids (5)
	   * Archimedean solids	(13)
	   * Convex prisms and antiprisms (2 infinite families)
	 * Nonconvex Uniform Polyhedra:
	   * Kepler-Poinsot polyhedra (4)
	   * Nonconvex uniform polyhedra (53)
	   * Nonconvex prisms, antiprisms, and crossed antiprisms
	     (3	infinite families)

       Representative samples of the prism sets	brings the total to 80 solids.
       Including  the dual of each brings the total up to 160.	(To create the
       "dual" of a polyhedron, faces are replaced with vertices, and  vertices
       with faces.)

OPTIONS
       --visual	visual
	       Specify	which  visual  to use.	Legal values are the name of a
	       visual class, or	the id number (decimal or hex) of  a  specific
	       visual.

       --window
	       Draw on a newly-created window.	This is	the default.

       --root  Draw on the root	window.

       --window-id number
	       Draw on the specified window.

       --delay number
	       Per-frame  delay,  in  microseconds.  Default: 30000 (0.03 sec-
	       onds.).

       --speed number
	       Larger numbers mean run faster.	Default: 1.0.

       --duration seconds
	       How long	before switching to a new polyhedron.  Default 12 sec-
	       onds.

       --wander	| --no-wander
	       Whether the objects should wander around	the screen.

       --spin [XYZ] | --no-spin
	       Which axes, if any, to spin around on.

       --titles	| --no-titles
	       Whether to display text describing each object.

       --which object-name
	       Display only one	particular object, identified by number, name,
	       or Whthoff symbol.

       --wireframe | --no-wireframe
	       Render in wireframe instead of solid.

       --fps   Display the current frame rate, CPU load, and polygon count.

KEY BINDINGS
       When running in a window, you can rotate	the  object  with  the	mouse.
       Also, the following keystrokes are defined:

       SPC or TAB  Select a new	polyhedron at random.

       + or >	   Select the next-higher-numbered polyhedron.

       - or <	   Select the next-lower-numbered polyhedron.

       ESC or ^C   Quit.

ENVIRONMENT
       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to  get	the  name of a resource	file that overrides the	global
	       resources stored	in the RESOURCE_MANAGER	property.

       XSCREENSAVER_WINDOW
	       The window ID to	use with --root.
